Me too, Daniella, I can't get comfortable and usually wake up from the pain and/or from being in an uncomfortable position. Sleeping with two RSD legs and arms isn't easy. The arms are being treated and it's going well so far, fingers crossed, but it's still awkward. I also have developed lower back pain and have some damage here and there (luckily not in the spine). It's thought to be due to bad posture from the RSD. Sleeping is hardly fun, I know. I can relate.
